This is an interesting corner case.
By default
round
returnsint
which can't represent non-finite numbers, so it throws various exceptions.When
ndigits
is provided,round
returnsfloat
, so non-finite numbers can be represented, and they just return what was passed in.Automerge-Triggered-By: GH:brandtbucher
